Product details
Overview
P4SMA220AHE3/5A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, rated for 220 V breakdown voltage (VBR = 209–231 V at IT = 1.0 mA), 328 A peak pulse current (IPPM), and 400 W peak pulse power (10/1000 µs waveform). It provides clamping protection for high-voltage DC rails in industrial power supplies and automotive control modules.
For engineers reviewing the P4SMA220AHE3/5A datasheet, P4SMA220AHE3/5A pinout, P4SMA220AHE3/5A application, or P4SMA220AHE3/5A equivalent, key selection criteria include its AEC-Q101 qualification, 185 V stand-off voltage (VWM), 0.91 µA max reverse leakage at VWM, and 300 °C solderability per J-STD-002 - critical for automotive-grade board assembly and long-term reliability under thermal cycling.
Technical Context
This device operates as a unidirectional clamping TVS, leveraging a glass-passivated silicon junction to achieve fast response (<1 ns) and low incremental surge resistance. Its 10/1000 µs waveform rating is derated above TA = 25 °C per Fig. 2, with maximum junction temperature of +150 °C and thermal resistance RθJA = 120 °C/W on standard 0.2" × 0.2" copper pads.
The P4SMA220AHE3/5A features matte tin-plated leads compliant with JESD 22-B102 whisker testing (Class 2), RoHS-compliant construction, and MSL Level 1 moisture sensitivity per J-STD-020. Polarity is marked by a cathode band; no marking is used for bidirectional variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 209 V / 231 V at IT = 1.0 mA - defines precise clamping onset threshold for overvoltage events |
| VWM | 185 V - maximum continuous reverse operating voltage before significant leakage begins |
| IPPM | 328 A (10/1000 µs) - peak transient current it can safely shunt without failure |
| VC | 328 V at IPPM - clamped voltage seen by protected circuit during worst-case surge |
| ID @ VWM | 0.91 µA - ultra-low leakage ensures minimal power loss in high-impedance bias networks |
| PPPM | 400 W (≤91 V); 300 W (>91 V) - peak pulse power handling capability under standardized surge conditions |
| TJmax | +150 °C - enables operation in under-hood automotive and industrial environments |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile case with matte tin-plated leads. Cathode indicated by band on body; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connects to protected line; conducts surge current to ground when VLINE exceeds VBR |
| Anode (unmarked end) | Reference node | Typically tied to system ground or low-impedance return path for clamping action |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220A-E3/52 | Same VBR range (209–231 V), but SMB package (DO-214AA); 600 W PPPM; higher IPPM (411 A) | Higher power handling suits larger PCB footprints; less space-constrained than SMA | Select when surge duty cycle demands >400 W or layout allows larger footprint |
| 1.5KE220A | Through-hole TO-204AE (DO-204AL); same VBR/VC; 1500 W PPPM; 6.8 A IFSM | Designed for manual assembly or high-reliability legacy systems; not surface-mount | Choose only for through-hole designs or where automated placement is unavailable |
Compared with SMBJ220A-E3/52 and 1.5KE220A, the P4SMA220AHE3/5A offers optimal balance of AEC-Q101 qualification, compact SMA footprint, and 400 W surge capacity - making it preferred for space-constrained automotive and industrial SMT assemblies requiring validated automotive reliability.

FAQ
What is the clamping voltage of P4SMA220AHE3/5A at its rated peak pulse current?
The P4SMA220AHE3/5A has a maximum clamping voltage (VC) of 328 V when subjected to its rated peak pulse current of 328 A under the 10/1000 µs waveform condition. This value is measured per standard test conditions defined in the Vishay datasheet and reflects the upper bound of voltage seen by protected circuitry during worst-case surge events. The P4SMA220AHE3/5A maintains this clamping performance across its specified operating temperature range.
Is P4SMA220AHE3/5A suitable for automotive applications?
Yes, P4SMA220AHE3/5A is AEC-Q101 qualified and explicitly designated for automotive use with ordering code suffix "HE3". It meets stringent requirements for temperature cycling, mechanical shock, and long-term reliability in under-hood and chassis-mounted electronic control units. The P4SMA220AHE3/5A is commonly deployed in 24 V power distribution networks and sensor interface protection within ADAS and body electronics modules.
What does the "HE3/5A" suffix indicate in P4SMA220AHE3/5A?
The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification, while "5A" specifies packaging in 13-inch diameter plastic tape and reel containing 7500 units. This configuration supports high-volume SMT assembly with industry-standard feeder compatibility. The P4SMA220AHE3/5A is distinct from non-automotive variants like P4SMA220A-E3/5A, which lack AEC-Q101 validation.
How does P4SMA220AHE3/5A compare to bidirectional TVS diodes in the same series?
The P4SMA220AHE3/5A is unidirectional and intended for DC line protection where polarity is fixed; it offers higher VBR (209–231 V) and VWM (185 V) than bidirectional variants (e.g., P4SMA220CA with VBR up to 220 V and VWM = 185 V). Bidirectional types handle AC or floating signals but exhibit symmetric clamping in both directions - a capability the P4SMA220AHE3/5A does not provide. Use P4SMA220AHE3/5A when protecting polarized DC rails.
What is the maximum reverse leakage current for P4SMA220AHE3/5A at its stand-off voltage?
The P4SMA220AHE3/5A exhibits a maximum reverse leakage current (ID) of 0.91 µA at its stand-off voltage (VWM) of 185 V, measured at TA = 25 °C. This ultra-low leakage ensures minimal power drain in high-impedance monitoring circuits and prevents false triggering in precision analog or logic interfaces. The P4SMA220AHE3/5A maintains this specification across its full operating temperature range per Vishay's characterization data.
